Refraction (Bent Thinking) #75

Proving Non-existence: when an arguer cannot provide the evidence for his claims, he may challenge his opponent to prove it doesn’t exist. Refutation: the burden of proof is one the one making the claim of existence. Examples: asking to prove God doesn’t exist or to prove UFO’s haven’t visited earth, and etc.). Side Note: Although one may prove non-existence in special limitations (e.g. by definition or demonstration within a small set), one cannot prove universal or absolute non-existence, or non-existence out of ignorance. It is very difficult to prove that something does not exist. The proof of existence must come from those who make the claims.
